The lock nut 40 is moved inwardly: to disengage it from the pins 42 whereupon the adjustingsleeve 33can be rotated to effect the proper adjustment of the roller sockets on their hinge pins23. It will thus .be appai ent that-the position of the roller 7 relative to the roller 5 can be readily adjusted as may I be desired without disconnecting the roller V anditsshaft.
